git-rev-list: Implement option to only print missing object
In the [partial clone demo](https://gitlab.com/chriscool/partial-clone-demo/-/blob/master/http-promisor/demo.txt#L37) we use the following command to count the missing objects:
```sh
git -C git-client1 rev-list --objects --all --missing=print | perl -ne 'print if s/^[?]//' | wc -l
```
Using `--missing=print` will print the missing objects, but prepend the hash with a `?`. Output will look something like this:
```
git -C git-client1 rev-list --objects --all --missing=print

Ideally there would be a command line option to only print the missing objects.
### Proposal
Add an optional argument `--print-only-missing` that only prints missing objects.
